DEVICE FOR ELEVATING AND SUPPORTING WEIGHTS.

SPECIFICATION forming part of. Letters Patent No. 726,928, dated May 5, 1903. Application filed July 26, 1902. Serial No. 117.098. (No model.)

To all whom it may concern:

Be it known that I, EDSON' HORNADAY, a citizen of the .United States, residing at 001- tax, in the county of Jasper and State of Iowa, have invented: certain new and useful Improvements in Devices for Elevating and Supporting Weights, of which the following is a specification.

The objects of myinvention are to provide a device of simple, durable, and inexpensive construction to be permanentlyatta-ched to an elevated support and by which an operator may place a bunch of bananas or other weight upon one end of the rope and then by pulling upon the other end elevate the weight to any desirable height, and then when the end of the rope upon which the operator is pulling is released it will be'automatically engaged and held to thereby support the weight in its elevated position, and the automatic holding device may be readily and quickly released by the operator by simply pulling downward upon the free end of the rope. v

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows an enlarged perspective view of the complete device with part of oneof the side pieces broken away. Fig. 2 shows a side elevation of the complete device at tached to an elevated support and showing a weight on one end of the rope and the ropeclamping device in its inoperative'position, one side of the frame being removed. Fig. 3 shows a similar View of a modification.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate two parallel side pieces of the machineframe, which are substantially L shape'in outline and which are connected by means of a cross-rod 11 at their tops and a cross-piece 12 near their lower ends, which hold the said side pieces slightly separated. Between the said side pieces and near the upper end thereof I have mounted a pulley 13 on the shaft toothed surface 16.

16 and the pawl 19.

let. Between the sides 10, near the lower end thereof, is a stationary block 15, having a At the lower end of this block 15 is a projection 17, having an opening 18 therein for purposes hereinafter made clear. Pivoted between the sides 10, adjacentto the toothed surface 16, is a pawl 19, having a toothed surface 20 adjacent to the toothed surface 16. The downward movement' of the pawl 19 is limited by means of a pin 21.

The reference-numeral 22 indicates a rope the central portion of which is passed over the 'pulley'13, and one end is passed through be- ;tween the sides 10 and against the inner surface ofthe cross-piece 12-to therebyhold the body portion of the device in a substantially ';vertical position and the other end passed between the sides 10 and between the toothed surface 16 and the pawl 19.

i g In the modified form shown in Fig. 3 the central portion of the rope is passed over the pulley.13. One end" is then passed through a pulley 23 and finally attached to. the projection 17, while the other end of the rope passes through between the toothed surface Iii-practical use and assuming the device to be suspended from an elevated support, which may be in the nature of a hook engaging the cross-rod l1, and assuming the rope to be in position, as shown in Fig. 2, it is obvious that the operator may, by pulling down- 'wardly upon the end of the rope that passes through between the toothed surface 16 and the pawl, readily elevate the weight attached to thefother end of the rope. When said weight has been elevated to the desired position, the operator swings the rope laterally until it engages the toothed surface of the pawl. He then permits the rope to move upwardly a slight distance, which will carry the pawl with it until the pawl clamps the rope between its end and the toothed surface 16.

Obviously, then, the operator may release his hold upon the rope and the weight willbe supported in its elevated position. When it is desired to lower the weight, it is only necessary for the operator to pull downwardly upon the free end of the rope until the pawl IOO drops. Then the free end of the rope may be permitted to move upwardly without engaging the pawl until the weight is lowered.

In the modified form shown in Fig. 3 the only change is that by means of the pulley 23 an operator may raise and lower a greater weight than would be possible without it. The free end of the rope is locked and released in the same manner, and the weight is attached to the pulley 23 instead of to the end of the rope.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-

1. In a device of the class described, the combination of a frame having two parallel side pieces, a cross-piece 12 near the lower end of said frame connecting the side pieces, a pulley 13 between the upper ends of the side pieces, a block 15 between the side pieces having a toothed surface 16, a pawl 19 pivoted between the side pieces and having a toothed surface 20 adjacent to the toothed surface 16, a stop 21 for limiting the movement of the pawl, and a rope passed over the pulley and having one end passed through between the side pieces and against the cross piece 12, and having the other end passed through the side pieces and between the block 15 and the pawl, substantially as and for the purposes stated.

2. In a device of the class described, the combination of a frame having two parallel side pieces, a cross-piece 12 near the lower 'end of said frame connecting the side pieces,

a pulley 13 between the upper ends of the side pieces, a block 15 between the side pieces having a toothed surface 16, a pawl 19 pivoted between the side pieces and having a toothed surface 20 adjacent to the toothed surface 16, a stop 21 for limiting the movement of the pawl, a pulley 23, and a rope passed over the pulley 13 and under the pulley 23 and having one end attached to the frame and the other end portion passed through between the toothed surface 16 and the pawl, substantially as and for the purposes stated.
